Something similar is happening with my connection to FFxp dev server. I am of course using 4.3.1 build 1975.
Server ends connection and ffxp is non the wiser, this whole thing sounds familiar to me. And of course the dev server is Proftpd.
Code:
[19:02:57] [R] Network Error (10054): Connection reset by peer
is what I get when I try to create a folder or transfer a file after the timeout has occurred. perhaps the server logs will tell more client side nothing aside from that, though I can post a full log in a bit as soon as it times out.
If this is unrelated ignore me.
